China claims to have successfully tested a hypersonic aircraft capable of reaching speeds in excess of Mach 6, or 4,563 miles per hour. The cutting-edge vehicle has the potential to penetrate US missile defence systems and be refitted to include a nuclear warhead.
The hypersonic glide vehicle (HGV), dubbed Starry Sky-2 (or Star-2), was launched on Friday, 3rd August from a site in northwest China, CNN reports. After being delivered to a height of 18 miles (30 km) by a multistage, solid-propellant rocket, the hypersonic aircraft assumed independent flight, reaching a top speed of Mach 6 (six times the speed of sound), which is about 4,563 miles per hour (7,344 km/h). The HGV maintained speeds above Mach 5.5 for nearly seven minutes, according to a statement released by the state-owned China Academy of Aerospace Aerodynamics (CAAA). Starry Sky-2, which took three years to develop, is now China’s first hypersonic aircraft.
During the test, the hypersonic vehicle made “large-angle turning manoeuvres” and other movements, the CAAA said. The HGV landed on its own, providing researchers with “effective” data for further testing and refinement. In addition to being China’s first hypersonic vehicle, the HGV is also the country’s first waverider aircraft—a type of hypersonic vehicle that improves its lift-to-drag ratio by using its shockwave as a lifting surface. The CAAA declared the test of Starry Sky-2 a “huge success.”
The purpose of the aircraft was not disclosed, but it has undeniable militaristic implications. The HGV could eventually be modified to carry both nuclear and conventional warheads. Hypersonic aircraft can penetrate missile defence systems, such as radar, owing to their high speeds and low incoming angles.
“China is a technology powerhouse in the way that the Soviet Union never was,” Peter W. Singer, fellow at New America and author of Ghost Fleet: A Novel of the Next World War, told Gizmodo. “It not only is developing its own cutting edge research, but it is also able to leverage the best ideas of the rest of the word, through partnerships, purchasing off the open market, and IP theft. The combination presents a technology challenger the likes of which the US military has never before faced.”
That said, China is still playing catch up to both the US and Russia, which have been working on hypersonic tech for nearly 20 years. Song Zhongping, a Hong Kong-based military affairs specialist, told the South China Morning Post that the Pentagon’s Hypersonic Technology Vehicle 2 (HTV-2) and Russia’s Avangard HGV can reach speeds close to Mach 20 (that’s 13,200 mph, or 21,245 km/h, in case you were wondering). And from 2010 to 2013, the US tested Boeing’s X-51 Waverider, which reached speeds of Mach 5. The US Air Force is hoping to deploy a fully functional hypersonic weapon by 2023.
Several months ago, Russia said it tested its first hypersonic missile, releasing some videos in July to make the world, especially the United States, aware of its newfound capability. Earlier in the year, Russian president Vladimir Putin said his country had developed a new nuclear-powered missile with unlimited range, but the claim remains unverified.
China’s announcement of a hypersonic vehicle comes at a time when trade tensions are high with the United States, leading some commentators to describe this latest test as a form of sabre-rattling. Regardless, the exercise shows that China is catching up quickly, and the US needs to take notice. [CNN, South China Morning Post]
